Leybold TRIVAC D16B pump

We used the rotary vane pump to vacuum the first spatial filter for TWIN system, this pump could not work two weeks ago. At first, we guessed the start capacitor was broken, however the pump did not work any more even we changed a new capacitor. Mike helped to separate the motor and the rotary vane, he found the motor worked well. The problem was the spider coupling was broken.
